SUBSOIL-PLOW.

Specification of Letters Patent.

Patented Sept. 26, 1911.

Application filed. January 20, 1911. Serial No. 603,723.

To all whom it may concern:

Be it known that I, JAMES M. Bnoons, a citizen of the United States ofAmerica, and a resident of Molena, county of Pike, State of Georgia,have invented certain new and useful Improvements in subsoil-Flows, ofwhich the following is a full and clear spccification, reference beinghad to the accompanying drawings, in which-- Figure 1 is a sideelevation of a plow embodying my improvements; Fig. 2 is a horizontalsection on the line 22 of Fig. 1; Fig. 3 a detail perspective view ofthe plow shank or standard, the plow share and landside bar beingremoved; Fig. l a perspective view showing a modification; Fig. 5 aperspective view showing a detail of the afore- Fig. 6 is a vertical sectional view of the modification shown in Fig. 4.

The object of the present invention is to provide a subsoil plow whichshall be simple and inexpensive in construction as well as durable andeflicient in operation; and this invention consists of certain novelfeatures of construction hereinafter described and claimed.

The plow shank or standard a consists of a wide flat. plate of sheetmetal having its front edge somewhat sharpened and having its upper endsuitably attached rigidly to the plow beam. The lower end of this platea is slitted vertically near its rear edge and also near its forwardedge and the portion of the metal between these slits is bent to oneside to form a seat I) for the plow shovel or scooter. The end portionsdepend below the seat Z) to form lugs or ears 0 to which are bolted, onthe landside, a landside bar (Z which inclines slightly upwardly andbackwardly and is beveled off downwardly at its front end to form anentering point c, this entering point being wider than the main or rearpart of the bar and being shouldered at f to abut against the forwardedge of the plow shank a.

The seat I) inclines upwardly and rearwardly to give the properinclination to the scooter or shovel g which is clamped down on itsupper face by a bolt It, the scooter or shovel being provided with alongitudinal slot 2' to provide for adjustment of the scooter or shovelto enable the same to be located properly with respect to the enteringpoint of the landside and to compensate for wear of the shovel orscooter. The seat 6 is slightly curved longitudinally so that when thescooter is clamped thereto there will be a slight resilient action, thisbeing advantageous in that it will render unlikely the stripping of thethreads of the bolt by excessive clamping action.

In the construction shown in Figs. 4: and 5, I provide for a doubleplow, that is, a plow in which a scooter or shovel may be supported ateach side of the plow shank. This is accomplished by riveting to theplow shank an additional plate 7' of sheet metal and providing the samewith a supplemental plow seat 70, similar in shape and arranged directlyopposite to the main seat 6. Depending ears Z on this plate j correspondwith the depending ears 0 on the main shank. This plate j has itsdepending edge bent outwardly, and the lower portion of the main part ofthe shank is similarly bent outwardly, thus forming a channel for thereception of the landside bar cl, this bar being fastened between theplates by suitable horizontal bolts 01. and the head of this bar beingshouldered upon opposite sides to abut against the forward edges of thefront ears 0 and Z.

It will be observed that my construction enables the plow to beconstructed of a very few parts which may be readily assembled and whichwill be strong and durable.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. A sub-soil plow, consisting of a beam,

a depending flat sheet metal shank or standard slitted vertically at itslower end at points at a distance from its forward and its rear edge,the portion of the shank between the slits being bent laterally andinclined upwardly and rearwardly, thus forming a plow seat I; and twodepending ears 0 integral with the shank, a plow blade fastencd to 'saidplate I) and abutting against the adjacent side of the shank, and alandside bar fastened to the depending ears 0 at the side of the shankopposite the plow and having its lower edge below the plate I) andco-incident with the lower ends of the ears 0, this land-side having itsforward end pointed and enlarged laterally, this enlargement forming avertical shoulder which abuts against the front edge of the front ear.

2. A sub-soil plow, consisting of a beam, a depending flat sheet metalshank or standard slitted vertically at its lower end at points at adistance from its forward and its rear edge, the portion of the shankbetween the slits being bent laterally and inclined upwardly andrearwardly, thus forming a plow seat I) and two depending ears 0integral with the shank, a plow blade fastened to said plate 6 andabutting against the adjacent side of the shank, the shank being bentlaterally at a point above the slits to off-set the plow supportingplate 6, a supplemental plate fastened to the shank at a point above theland-side bar and provided with depending ears Z and an integral plowsupporting plate is similar to the aforesaid plate 7), and a land sidebar clamped rigidly between the ears of the shank and the ears of thesupplemental plate and having their lateral shoulders at its enteringpoint which I abut against the front ones of said ears.

In testimony whereof I hereunto afliX my signature in the presence oftwo witnesses this 17 day of Jan. 1911.
